[0040] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0041] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0042] Technologies and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such technologies and equipment should be considered part of the specification.

[0043] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0045] This invention provides a printing mechanism that enables rapid printing of workpieces during the production process, thereby improving printing efficiency. The workpiece can be a silicon wafer or other materials.

[0046] like Figure 1 and Figure 2 As shown, the printing mechanism provided by this utility model includes:

[0047] Conveying structure 1, turntable structure 2, and printing structure 3;

[0048] The conveying structure 1 is disposed on the turntable structure 2;

[0049] The printed structure 3 is located above the turntable structure 2.

[0050] Specifically, the conveying structure 1 can be a single-rail conveying system or a dual-rail synchronous conveying system, so as to simultaneously convey one or two workpieces, facilitating subsequent printing processes. Positioning the conveying structure 1 around the turntable structure 2 facilitates workpiece loading and unloading.

[0051] like Figure 1 and Figure 2 As shown, the conveying structure 1 may include a first conveying section and a second conveying section. The first conveying section is used to convey the workpiece to be printed onto the turntable structure 2, while the second conveying section is used to convey the printed workpiece from the turntable structure 2 to the next workstation. The conveying direction of the first conveying section and the conveying direction of the second conveying section can be set to be consistent, allowing the workpiece to be printed quickly during the conveying process and avoiding affecting the production cycle.

[0052] Specifically, the turntable structure 2 has a direction along the first direction, for example... Figure 1 The loading station, printing station, and unloading station are arranged in a counter-clockwise direction. These three stations can be evenly or non-evenly distributed. When the turntable structure 2 moves along the first direction, for example... Figure 1 When rotated counterclockwise, the turntable structure 2 can drive the workpiece at the loading station to the printing station for printing and then to the unloading station for unloading, which facilitates the printing cycle.

[0053] To avoid interference between the printing process of printing structure 3 and turntable structure 2, the printing head of printing structure 3 can be set higher than that of turntable structure 2. After printing is completed, turntable structure 2 continues to rotate along the first direction to the unloading station, so that it can be transported from the unloading station to the next station.

[0054] The turntable structure 2 may include a turntable body and a drive unit, the drive unit being used to drive the turntable body to rotate. The turntable body may also have an adsorption unit, which is used to adsorb workpieces placed on it, thereby ensuring the stability of the workpieces during the rotation of the turntable body, avoiding printing defects caused by displacement, and thus ensuring printing reliability.

[0055] Compared to traditional printing mechanisms, the printing mechanism provided by this utility model utilizes the rotation of the turntable structure 2 for workpiece transport and printing. This enables efficient printing while facilitating the flexible arrangement of the printing structure 3. It also makes it easier for operators to maintain the printing structure 3 located on the outer periphery of the turntable structure 2, thereby reducing maintenance costs and difficulties.

[0056] Optionally, the turntable structure 2 has a loading station, a printing station and a unloading station arranged in sequence. When the conveying structure 1 conveys the workpiece to the loading station, the turntable structure 2 can rotate and drive the workpiece through the printing station to the unloading station.

[0057] Specifically, the turntable structure 2 has a direction along the first direction, for example... Figure 1 The loading station, printing station, and unloading station are arranged in a counter-clockwise direction. These three stations can be evenly or non-evenly distributed. When the turntable structure 2 moves along the first direction, for example... Figure 1 When rotated counterclockwise, the turntable structure 2 can drive the workpiece at the loading station to the printing station for printing and then to the unloading station for unloading, which facilitates the printing cycle.

[0058] Optionally, the printing structure 3 includes an adjustment support 31 and a printing part 32. The printing part 32 is disposed on the adjustment support 31, and the adjustment support 31 can drive the printing part 32 to perform translational and / or rotational movements.

[0059] like Figure 1 As shown, based on the different position information of the workpiece at the loading station, the adjusting support 31 can drive the printing unit 32 to move and / or rotate, thereby achieving position adjustment and placing the printing unit 32 in the corresponding position. This corresponding position ensures the reliable implementation of subsequent printing processes, thereby reducing printing defects and improving the printing yield.

[0060] Optionally, it also includes a detection structure 4, which is located at the loading station of the turntable structure 2 and is used to perform pre-printing detection on the workpiece at the loading station. The detection structure 4 is signal-connected to the adjustment support 31 so as to transmit the detection information to the adjustment support 31.

[0061] like Figure 1 As shown, the detection structure 4 includes, but is not limited to, a camera and a sensor. The detection structure 4 is used to detect the position information of the workpiece after loading and transmit the position information to the adjustment support 31 so that the adjustment support 31 can adjust the printing section 32 based on the position information, thereby adapting to the printing of workpieces in different positions and improving the reliability of printing.

[0062] In another embodiment, a detection device can also be set at the unloading station. The detection device includes, but is not limited to, a camera and a sensor. The detection device is used to detect the printing status of the workpiece after printing so as to determine the printing effect of the printed workpiece.

[0063] Optionally, the printing structure 3 further includes a first driving member 33, which is disposed on the adjusting support 31, and the printing part 32 includes a printing screen 321, which is connected to the driving end of the first driving member 33.

[0064] Driven by the first driving member 33, the printing screen 321 can move along the height direction and move closer to or further away from the printing station of the turntable structure 2.

[0065] like Figure 1 and Figure 3 As shown, the first driving component 33 includes, but is not limited to, a linear motor and a cylinder. Under the forward drive of the first driving component 33, the printing screen 321 can drive the printing head to descend along the height direction of the printing structure 3 to the working position, where convenient printing can be achieved. After printing is completed, under the reverse drive of the first driving component 33, the printing screen 321 can drive the printing head to rise along the height direction of the printing structure 3 to the avoidance position, where convenient transport of the printed workpiece can be achieved, avoiding interference with the transport process.

[0066] Optionally, the printing section 32 further includes a printing element 322 and a second driving element 323. The printing element 322 extends into the printing screen 321, and the printing element 322 is connected to the driving end of the second driving element 323.

[0067] Driven by the second driving member 323, the printing member 322 can move and print on the workpiece located at the printing station.

[0068] like Figure 1 and Figure 3 As shown, the printing head 322 is used to print on the workpiece located at the printing station. The second driving component 323 includes, but is not limited to, a linear motor and a cylinder. After the printing screen 321 drives the printing head 322 to descend to the working position along the height direction of the printing structure 3, the printing head 322 can move horizontally under the drive of the second driving component 323 and print on the workpiece located at the printing station.

[0069] The printing element 322 is designed so that its end extends into the hollow area of ​​the printing screen 321, thereby limiting the movement of the printing element 322 by utilizing the side wall of the printing screen 321, thus ensuring the reliability and controllability of the movement of the printing element 322.

[0070] Optionally, the turntable structure 2 includes a motor assembly 23, and the second drive member 323 is located on the side of the adjusting support 31 near the motor assembly 23.

[0071] This configuration allows the printed part 322 to be placed outside the printing mechanism, greatly shortening the distance between the printed part 322 and the printing screen 321 and the operator, facilitating operation, maintenance, and the addition of paste, thereby reducing maintenance costs and difficulty.

[0072] Optionally, the printed part 322 includes a first cutter head 3221 and a third drive member 3222, wherein the drive end of the third drive member 3222 is connected to the first cutter head 3221;

[0073] Driven by the third driving member 3222, the first cutting head 3221 can descend and abut against the printing screen 321.

[0074] like Figure 4 As shown, the third driving component 3222 includes, but is not limited to, a linear motor and a cylinder. During printing, the third driving component 3222 first drives the first cutter head 3221 to descend until it abuts against the printing screen 321. Then, the second driving component 323 drives the printing component 322 to move horizontally to perform screen printing on the surface of the workpiece to be printed. Finally, the third driving component 3222 drives the first cutter head 3221 to rise.

[0075] like Figure 5 As shown, the printed part 322 may further include a second cutter head 3223 and a fourth drive member 3224. The drive end of the fourth drive member 3224 is connected to the second cutter head 3223. The fourth drive member 3224 includes, but is not limited to, a linear motor and a cylinder.

[0076] During printing, the third drive unit 3222 first drives the first cutter head 3221 to descend until it abuts against the printing screen 321. Then, the second drive unit 323 drives the printing piece 322 to move and screen print on the surface of the workpiece to be printed. After that, the third drive unit 3222 drives the first cutter head 3221 to rise. Then, the fourth drive unit 3224 drives the second cutter head 3223 to descend until it abuts against the printing screen 321. Then, the second drive unit 323 drives the printing piece 322 to move in the opposite direction and smooth the surface of the workpiece to be printed. Finally, the fourth drive unit 3224 drives the second cutter head 3223 to rise.

[0077] The first cutting head 3221 and the second cutting head 3223 are positioned opposite each other. This allows the first cutting head 3221 to print on the workpiece first, and then the second cutting head 3223, moving in the opposite direction, to smooth the printed surface, thereby improving the printing effect.

[0078] Optionally, the turntable structure 2 includes a turntable body 21, a fixed base 22, and a motor assembly 23. The motor assembly 23 is connected to the fixed base 22, and the output end of the motor assembly 23 is drively connected to the turntable body 21. Figure 1 , Figure 2 , Figures 6 to 8 As shown, driven by the motor assembly 23, the turntable body 21 can rotate and transfer the workpiece on it.

[0079] Optionally, the motor assembly 23 includes a motor coil 231, a motor rotor 232, an adapter 233, and a rotor spindle 234. The motor coil 231 is connected to the fixed base 22. One end of the adapter 233 is connected to the motor rotor 232, and the other end of the adapter 233 is connected to the rotor spindle 234. The rotor spindle 234 is connected to the turntable body 21.

[0080] When the motor coil 231 is energized, the motor rotor 232 can drive the adapter 233, the rotor spindle 234 and the turntable body 21 to rotate together.

[0081] like Figure 7 and Figure 8 As shown, a bearing may be provided on the fixed base 22, and the rotor spindle 234 is connected to the inner ring of the bearing. The turntable body 21 is connected to the side of the rotor spindle 234 away from the adapter 233, so that when the motor coil 231 is energized, the motor rotor 232 can rotate, and drive the adapter 233, the rotor spindle 234 and the turntable body 21 to rotate together, thereby realizing the switching between different work positions.

[0082] The motor rotor 232, adapter 233, rotor spindle 234 and turntable body 21 are arranged coaxially to ensure reliable transmission of driving force.

[0083] Optionally, it also includes a grating 5, which is disposed on the rotor spindle 234. The fixed base 22 is also provided with a reading part 221. The reading part 221 and the grating 5 together detect the rotation angle of the rotor spindle 234.

[0084] like Figure 7 and Figure 8 As shown, the grating 5 can be a circular grating, which is set on the outer periphery of the rotor spindle 234, with the reading section 221 facing the circular grating. When the infrared light-emitting diode in the reading section 221 emits light towards the grating 5, the reflected light can be returned to the photodetector through the optical system in the reading section 221 to realize the detection of the rotation angle of the rotor spindle 234, thereby enabling convenient control of rotation and facilitating the drive of the turntable body 21 to quickly and accurately reach the corresponding work position.

[0085] Optionally, the reading unit 221 includes a reading head and a bracket, the bracket being movably connected to the fixed base 22, and the reading head being disposed on the bracket.

[0086] Specifically, a waist-shaped hole can be made on one of the bracket and the fixed base 22, and a sliding pin can be set on the other of the bracket and the fixed base 22. The position of the bracket on the fixed base 22 can be adjusted by the movement of the sliding pin in the waist-shaped hole, such as the front-back position and the left-right position, so as to achieve a better detection effect.

[0087] Optionally, it also includes a water-cooling jacket 6, which is fitted onto the outer periphery of the motor assembly 23. For example... Figure 8 As shown, a cooling medium flows inside the water-cooling jacket 6, which can dissipate heat from the motor coil 231, preventing heat buildup that could damage the motor coil 231 and thus extending the service life of the printing mechanism.

[0088] like Figure 8 As shown, a protective component 7 can also be provided at the bottom of the motor assembly 23. The protective component 7 can improve the structural reliability of the turntable structure 2 while also isolating heat.

[0089] like Figure 1 As shown, it also includes a rotating structure 8, which faces the conveying structure 1. The rotating structure 8 can rotate the workpiece conveyed on the conveying structure 1 to a suitable printing angle so as to facilitate the efficient execution of subsequent printing processes.

[0090] In addition, when transporting other workpieces, the rotation angle of the rotating structure 8 can be set to other suitable angles according to the specific structure of the workpiece.

[0091] like Figure 1 As shown, it also includes a straightening structure 9, which may include straightening columns, straightening blocks, straightening wheels, etc. that are arranged opposite to each other. The straightening structure 9 can align and correct the workpiece before it is fed, thereby ensuring the reliability of subsequent processes.

[0092] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
